There was a bunch of stuff in the cross section that haddn't had any
attention in a while. I might need to slim it down later, but this is
good for now.
$(shell ...) looks a little sketch like it will be run no matter what.
And there are problems building the manual on darwin so hopefully this
fixes them.
The function buildGoModule builds Go programs managed with Go modules. It builds
a Go module through a two phase build:
- An intermediate fetcher derivation. This derivation will be used to
fetch all of the dependencies of the Go module.
- A final derivation will use the output of the intermediate derivation
to build the binaries and produce the final output.
Especially older hardware doesn't support AVX instructions. DLib is
still functional there, but significantly slower[1].
By setting `avxInstructions` to false, DLib will be compiled without
this feature.

Whenever we create scripts that are installed to $out, we must use runtimeShell
in order to get the shell that can be executed on the machine we create the
package for. This is relevant for cross-compiling. The only use case for
stdenv.shell are scripts that are executed as part of the build system.
Usages in checkPhase are borderline however to decrease the likelyhood
of people copying the wrong examples, I decided to use runtimeShell as well.
The appimageTools attrset contains utilities to prevent
the usage of appimage-run to package AppImages, like done/attempted
in #49370 and #53156.
This has the advantage of allowing for per-package environment changes,
and extracts into the store instead of the users home directory.
The package list was extracted into appimageTools to prevent
duplication.
Since #53055 was merged the Makefile for the manual could not be run
correctly as the generated function documentation was included, but
not actually generated.
This adds the necessary generation step by first building the XML file
containing function locations and preserving its store path in a
variable, which is then used both for linking of the locations file
and as a build input for the function docs generator.
This fixes #55014
Comments on conflicts:
- llvm: d6f401e1 vs. 469ecc70 - docs for 6 and 7 say the default is
to build all targets, so we should be fine
- some pypi hashes: they were equivalent, just base16 vs. base32
This is useful when running tools like NixOps or nix-review
on workstations where the upload to the builder is significantly
slower then downloading the source on the builder itself.
We can't run the checkPhase when build != host, so we may as well make
the checkInputs native.
This signicantly improves the situation of Python packages when enabling
strictDeps.
Currently the manual scales to the view port of the browser.
This leads to an unreadable layout and I found myself
reading the xml source instead.
The optimal width would be around 50 characters per line.
Since we have code listings also in the manual I relaxed
this limit a bit towards 70 characters per line.
Modifies the build process of the manual to invoke nixdoc
automatically to generate XML files with function documentation.
Currently documentation is present for five of the files in `lib/`.
To add another file to the generated docs, both
`doc/functions/library.xml` and `doc/lib-function-docs.nix` must be
updated.
Since Intel's default openmp implementation is available in the same src
tarball, we can just include it in the package. This means that `mkl` now "just
works" without any environment variables, fragile setup-hooks, or forced
propagation.
Since the openmp implementation is only needed at runtime (and for test cases),
users can substitute a different one if they prefer by exporting it with
`LD_PRELOAD`, which is how Intel recommends handling this. If they do not do so,
`libiomp.so` lives next to `libmkl_rt.so` and thus will be in the RPATH as a
sane default.
Since this still comes from the same src tarball, we can ship it without losing
the fixed-output derivation; likewise, since Hydra is not building or caching
these, shipping these proprietary packages costs no bandwidth for the nix
community.
To make updating large attribute sets faster, the update scripts
are now run in parallel.
Please note the following changes in semantics:
- The string passed to updateScript needs to be a path to an executable file.
- The updateScript can also be a list: the tail elements will then be passed
to the head as command line arguments.
Encouraging to put container elements on their own lines to minimize
diffs, merge conflicts and making re-ordering easier.
Nix doesn't suffer the restrictions of other languages where commas are
used to separate list items.
